We describe a methodology to automatically turn arbitrary ARMv8 programs into alphanumeric executable polymorphic shellcodes. Shellcodes generated in this way can evade detection and bypass filters, broadening the attack surface of ARM-powered devices such as smartphones.

We present colour-magnitude diagrams of open clusters, located in the range 112◦ < l < 252◦, manifesting stellar populations in the background of clusters. Some of the populations are found to be located beyond the Perseus arm and may be the part of Norma-Cygnus (outer) arm. The outer arm seems to be continued from l ∼ 120◦ to l ∼ 235◦. The background populations follow the downward warp of the...

Systematic studies of identification efficiency for e/n/p were performed in a variety of noble gas mixtures and in pure hydrocarbons at pressures up to 5 atm using a 15 GeV/c tagged beam. Neon mixtures were found to give the best results (6.7 (I n/p separation at 1 atm). Replacing the conventionally used argon by neon would permit a reduction of detector depth by almost a factor of two. The mea...

Most embedded systems are designed to perform one or fewer specific functions. It is important that the hardware and the software must closely interact to achieve maximum efficiency in all of these realms and overcome the drawbacks found in each aspect. This research focuses on designing a totally new Instruction Set Architecture (ISA) as well as hardware that can closely tie together with the ...

AMULET3 is a fully asynchronous implementation of ARM architecture v4T and was designed at the University of Manchester between 1996 and 1998. It is the third generation asynchronous ARM, and is aimed at a significantly higher performance level than its predecessors. Achieving this higher performance has required significant enhancements to the internal micro-architecture, such as the introduct...

Processors nowadays are consistently equipped with debugging features to facilitate program analysis. Specifically, the ARM architecture involves a series of CoreSight components and debug registers aid system debugging, group authentication signals designed restrict usage these registers. Meanwhile, security is under-examined since it normally requires physical access use in traditional model....
